Defensive publication

ABSTRACT

DIOL MONOETHERS CONTAINING A NEOPHENTYL STRUCTURE ARE PREPARED BY THE CATALYTIC HYDROGENATION OF CERTAIN CYCLIC DIETHERS AT ELEVATED TEMPERATURES AND PRESSURES. DIOL MONOETHERS HAVING A QUATERNARY CARBON ATOM ARE PARTICULARLY USEFUL, FOR EXAMPLE, AS SOLVENTS AS HIGH-TEMPERATURE FUNCTIONAL FLUIDS OR AS INTERMEDIATES FOR OTHER USEFUL CHEMICAL COMPOUNDS SUCH AS PLASTICIZERS AND WETTING AGENTS.

Int. Cl. C07c 43/00 US. Cl. 260-615 No Drawing. 11 Pages Specification Diol monoethers containing a neopentyl structure are prepared by the catalytic hydrogenation of certain cyclic diethers at elevated temperatures and pressures. Diol monoethers having a quaternary carbon atom are particularly useful, for example, as solvents, as high-temperature functional fluids or as intermediates for other useful chemical compounds such as plasticizers and wetting agents.
